Application led August 28,1926, Serial No;

This invention relates to an improved method ofY affixing rubber heels or other additionall wearing surface elements suitable for affixingon the lbase of a heel of a shoe,

v inV which the additional wearing member is replaceable when it becomes Worn bya like member. More particularly does thepresent; invention relate' to detachablev heel pieces off the type in which the detachable heel meinn ber has a hard portion on its upper or inner face which is provided with kan aperture or recess to receive a resiliently supported projection carried by a co-operating member secured to the shoeheel, the method of attaching the heel member to the said cooperating member being by sliding one within the other by means of a co-operating `projection and channel, until the resiliently supported projection engages in thesaid aperture or recess.

According to the present invention a detachable heel member of the above type comprises a plate adapted to be secured to the baseof a shoe heel and carrying a leaf spring or resilient finger upon which -is provided a projectiony adapted -to engage in an aperture `in a part of the detachable heel member.

In the preferred embodiment of my invention I provide a metal or other suitable hard platey having aperiphery shaped to correspond with the outline of the heel to which it is to be attached, a further plate being secured upon the aforementioned plate and carrying on its inner face a leaf spring or resilient finger which is accommodated in a recessed or cut-away portion of the first mentioned plate, achannel or cut-away portion in thesecond mentioned plate adapted to receive a projection carried by there placeable heel member,` the ksaid projection having an aperture adapted to receive a projection `carried by the said leaf spring or resilient finger, the said replaceable heel member having anaperture in its wearing surface registering with the aperture in its said projection whereby a suitable tool may be introducedy to depress the said projection to enable the wearing surface'member to be slid out of place and if desired a new one substituted. f l 1 Inorder that my invention may be clearly understood and readily carried into effect7 I have appended hereto a sheet of drawings 132,295, and mei-@atentan July 2e, 192e.

'illustrating the`v preferred embodiment of same, and ywherein Fig. l is a. plan viewof the outer face of the plate carrying the leaf spring or spring 'finger and having the recess or channel to receivek the projection 'carried by the `re Fig. 3 is a section to a larger scale on the 65 line A-B of Fig. l.l

Fig. 4 is a section on the line C-D of Fig. l, and v Fig. 5 is a plan View of the inner or upper face of the replaceable wearing surface 70y member.

Referring to the drawings the heel of a shoe is indicated by the reference numeral l (see Figs. 3 and 4). The detachable wear ing surface member 2 is preferably shaped 75 to correspond in outline with the outline of the shoe heel and may be composed of rubber, leather or other suitable material. The member 2 has attached to it by splayed rivets 3 or other suitable means a projection 4 80 which is preferably of metal, butk may be composed of other hard substance.

The projection 4 is disposed upon the in` ner or upper face of the wearing surface member 2 and it is of shallow dovetail cross 875v section (see 3) whereby it may be slid into a correspondingly shaped opening 5 in a plate 6 which is secured to the shoe heel l by screws or other suitable elements 7. The

innerend of the projection V4 is preferably 9b radiused as indicated at 4a, the opening 5 also being correspondingly radiused as shown at 5a. i

The dovetail section of the opening 5 and the projection 4 prevent the heel member 2 95 from dropping from the plate 5, and to prevent the projection 4 from sliding endwise out of ythe plate 5, a. resiliently supported i projection 8 is provided adapted to enga-ge in a central opening 9 passing completely 100 through the member 2 and the projection 4. yIhe projection 8 is rounded to enable'the j projection 4 to be slid over it when aixing the member 2. rifo facilitate the initial part of the operation of sliding the projection 4 195 into the opening 5, the leading edge of the projection 4 is formed with a rounded recessed portion 10.

The locking projection 8 is carried by the free end of a resilient strip 11 secured by a rivet 12 or other suitable means to the plate (3. The spring l1 is accommodated in a channel 13, which is obtained by forming a slot in a plate 14 interposed between the plate 6 and the heel l of the shoe.

lllhen itis desired to remove a worn heel member 2, it is only necessary to insert a tool in the opening 9 to depress the projection 8 and to press the member 2 endwise to slide the projection 4t out of the opening 5.

A detachable heel piece for footwear comprisingl in combination a base plate for X- ture to a shoe heel, having a dovetailed opening forwardly extending :trom the curvedL back of the heel, a downwardly-urged spring tongue permanently xed to the upper face of said base plate, extending in a rearward direction to beyond the inner extremity of the dovetailed opening and terminating at its free end at approximately the centre of the heel, a thin intermediate plate for interposition between the base plate and the shoe heel with a slot extending completely through it shaped to conform to the spring tongue and adapted to accommodate said tongue, a downward locking projection on the free end of the tongue, and a detachable wearing member having` a dovetail projection extending forwardly from its curved rear edge and a hole extending through the complete thickness of both the wearing member and dovetail projection for receiving the locking projection of the springl tongue, and allowing insertions of an unlocking tool.
